THOMAS CURRAN,'OF STEEATOR, ILLINOIS.

. HATER-CONTROLLING DEVICE.

Application filed Sept mber 22, 1921. serial a... 502,484. a

To all whom it conceww I Beit known that LTHoM s CURRAN, a

citizeno'lithe United States, and a resident of Streator, inthe countyofLa Salle and State of Illinois, have invented a new and permitting theuse of a gate valve for the control of thewater, which valve provides afree way flow of water-to the standpipe.

A further object of my invention .is to provide a water controllingdevice that is thoroughly practical" i:'or the purpose intended and notlikely to get out of order easily. I

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointedoutin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which Fig. 1 is a side elevation of my watercon-- trolling device,

Fig. 2 is a sectlon of a part of the device,

Fig. 3 is a section of a part of the device along the line 3-3 of Fig.1,

Fig. 4 is a diagrammatic view of the operating valves with the gatevalve open,

Fig. 5 is a diagrammatic View of the operating valves with the gatevalve closed.

In carrying out my invention, I make use of a standard gate valve 1,having an elongated spindle 2. The valve 1 is connected to a water main3 at one of its portsand to a discharge main 4 at its other port.Supported above the valve 1 by uprights 5 is a cylinder 6 having itsends. closed by means of plates 7 and 8. The plates 7 and 8 are held inclosed engagement with the cylinder 6by the use of tie rods 9, makingthe cylinder water tight. Within the cylinder, 6 and secured to thevalve stem 2 is a piston.

10. .The piston 10 consists of two leather,

, circular members 11 fixed to twosteel plates f I 12 which plates aresecurely bolted together.

A rod 13 vertically disposed upon the piston 10 and in alinement with.,thevalvestem2 projects through the plate"7 and engages compressionspring 14. The spring .14 is normally confinedbetween the platesr15 and.16, whichplatesare supported .above the cyl- .inder 6 by means oftherods 17. The rods 17 are secured was plate '7. It will be evidentthat-the rod 13 could :bereplaced'by an extension of the valve stem 2,bu-t for. the sake of .ease in assembly of the device, .1

have .used the rod 13. Extending upwardly are'two three-way valves -20,andv 21. The

,from the water'main 3 is a pipe 18 provided 5 with. a valve 19.Connected with thepipe 18 The plates; 'and8 are providedwith vents and23 which are, connectedea ch to av 7 port of the valves 20 'and2l,respectively. .30. I

A discharge pipe24 is providedand isv connected by means of two pipes 25and 26 each to. a port OfthevalVes-Z O and 21," respec-;;1; vtively.QThe cylindero is provided with an additional vent 27 through thefplate8,

which vent is connected to a simple valve 28.

The valves 20, 21 and 28 are all devised to."

operate at approximately aquarter of a revolution and are each providedwith arms 29.

a bar 30 which bar in turn is pivotally se- The arms 29 are pivotallysecured to] cured to a lever 31. .{lhe lever 31 terminates.

in a ring 32 which is concentric with an upright discharge pipe 33. Thestructure is clearly. shown in Fig. 3. "The lever 31 is actuated bymeans of a vertical rod 34, which has provided at its lower end aflattened portion 35 having two outwardly project ing fingers 36, whichfingers engage the ring 32 as is shown in Fig. 1. At the opposite end ofthe vertical rod 34 is ,a bell-crank 37 which is tied by means of 'arod' 38 to a hand lever 39. The hand lever 39 is piv-' otally mounted tothe spout 40 at 41.

The discharge pipe 33 carrying the spout i 40 is pivotally. mounted to abase 42 at 43' may be swung into any desired so that it position. i

From the foregoing description. of the various parts of the device, theoperation thereof may be. readily understood. The device,.

as; shown in Fig. 1, is shut oil and the valves are in the position asindicated in Fig. 5.

When it is desired to turn on the flow of water in the spout 40, theoperator moves the hand lever 39 in a downward direction.

This causes the lever 31 to assume the posivalve and'into the vent 23 atthe lower part of the cylinder-6. The vent 27 at this time is closedandthe valve 20, is turned so as to permit any water that may be abovethe piston-10 in the cylinder to pass out through the vent 22 ando-ut ofthe discharge pipe 2-1. It will be seen, therefore, that water enteringthe vent 23 will cause the piston 10 to rise, carrying with it the valvestem 2 and thus open the gate valve. The spring 14 at, this, time iscompressed.

To shut off the water, the lever 39 is moved back to they position shownin Fig. 1., The valves 20, 2.1 and 28 are thus moved to the positionshown in Fig. 5. With the valves 20, 21 and 28 in this position, waterin the cylinder 6 below the piston 10 will be discharged through thevent 2-3 and through the discharge port 44 of the valve 21. Water willalso be discharged from, below the piston 10 through the vent 27 of thevalve 29-, thus providing a double discharge below the piston while thegate valve is being closed. The valve 1 is closed by means of waterentering the upper part of the cylinder 6 through the valve 20 and bymeans oi? the spring 14: bearing down upon the rod 13, which rod is atall times in close engagementwith the piston 10.

I claim:

The combination with a gate valve having avalve stem, a water mainconnected with the valve, and aspring for exerting a downward pressureupon said valve stem to yieldably close said valve, of a cylinderdisposed adjacent to said valve, 2. piston within said cylinder, a rodconnecting said piston with said valve stem, a valve having three ports,one port'eonnected with said water main, another communicating with theinterior of said piston at its upper end, and the third connected with adischarge pipe, a second valve having three ports, thev first port beingconnected with said water main,

the second port communicating with said cylinder at its lower end, andthe third port communicating with said discharge pipe, a third valvehaving one port communicating with the lower end o-f'said cylinder, andthe others with a discharge pipe, and means for actuating said valves:simultaneously, whereby water may enter from said main into the. upperportion of said cylinders" to cause said piston to move downwardly, and

water within said cylinder may bedischarged through the tworemainingvalves associated with the lower end of the cylinder to cause said gatevalve to close.
